Class algebra.table

public class table extends entity implements Drawable, Cloneable {}

This class holds a table of Words with the row and column headings and the most interesting of all!!

Field Index:

int rows
int cols
vector row_heading
Since we do not know the number of rows at the beginning I declared them to be vector
which is a subclass of java.util.Vector with some added functionality. It is in fact a vector
of Words.
vector col_heading
Though we know the number of columns, it has been declared as a vector for the sake of
uniformity. This is also a vector of Words.
vector values
This contains the values inside the table. It is also a vector but its elements are arrays of
Words of length cols. That is, values holds rows ( each is an array of Words of length cols. )

Constructor Index:

table()
table( int c )
table( int r, int c )

Method Index:

Object clone()
int get_cols()
int get_rows()
Words get_value( int i, int j )
This returns the element(Word(s) ) in the 'i'th row and 'j'th column.
void add_row_heading( vector val )
This just creates a clone of the incoming vector 'val' and assigns it to row_heading. The
vector 'val' infact has Words ( shall we say an array of Words! ) that are built in the
application applet which are individual exercises.
void add_col_heading( vector val )
Same as above.
void add_row( Words[] val )
This appends the incoming array of Words( which are in fact individual rows ) to the vector
values.
void draw( Graphics g, integer W, integer H, integer X, integer Y )
Each column in this table is of fixed width. It is the maximum size() of the Words in
col_heading and values. Within each column the Words are right justified.
